To all whom it may concern.-

Be it known that I, Fannnnrc SANDERS, a subject of the Emperor of Germany, residing at St. Petersburg, in the Empire of Russia, merchant, have invented Improvements in Apparatus for Removing Sewage or other Impurities from Oesspools, Sinks, and the Like; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for evacuating cesspools, sinks, sewers, and other reservoirs in which filth and impurities are accumulated. t

The apparatus is contained within the pit or reservoir, arranged between the pumping-station and the street service-pipes or sewagepipes, and constitutes a means of transmitting to the said pipes the filth and impurities introduced into the pit or reservoir under sufficient pressure to carry the fluids and substances forward, as required.

In the drawings are represented different forms and arrangements of apparatus for the purpose, but all adapted toevacuate the pit or reservoir by means of an ejector fitted on the topof a cylindrical vessel provided with an inlet-valve from the pit or reservoir and an outlet to the ejector, such ejector being in communication at one end with the pipe leading from the pumping station and at theother end with the pipe leading to the street servicepipes or sewagepipes.

Figure 1 represents a pit or reservoir, A, constructed of any suitable impermeable material not subject to corrosion,with an incline, as shownat Rand a hermetically-closed cover, B, with a man-hole, E. In this cover is fitted a tube or hopper, O, with a valve, D, at the bottom provided with. a counterpoise or weight, d, through which the impurities are admitted into the pit or reservoir A, which contains a cylindrical vessel or apparatus 9, having on its top an ejector, H, and at the bottom an inlet-valve, K. The ejector H is in communication with the inlet-pipe I, and has an outlet-pipe, S, connecting the ejector with the street service-pipe or sewage-pipe T. The

pipe I, which is opened or closed, asrequired, by the cock M, has a branch pipe, L,wl1ich is openedor closed, as required, by the cock N, and leads to a perforated hollpw ball, 0. When it is required to force the impurities out of the pit or reservoir A, the cock M is opened, and the pipe I, being in connection with some water or disinfectingfluid pumping-station, water or disinfecting-fluid will be forced into the ejector H under high pressure. The ejector in its working causes the impurities to pass from the pit or reservoir A into the vessel 9, wherein a partial vacuum is created by the action of the ejector. As soon as the impurities enter the ejector H, they are forced by the water 'or disinfecting-fluid under high pressure into the service-pipe or sewage-pipe T. When the pit or reservoir A has been emptied, the cock N may be opened for a short time, so that both the cooks M and N willbe open at the same time, in which case'water or disinfecting-fluid will also be forced under high pressure through the pipe L into the perforated ball O,whence it will be forced againstthe walls of the pit or reservoir A and cleanse the walls from the impurities remaining thereon. After such washing or cleansing operation both cocks M and N can be closed until the pitor reservoir A requires to be emptied again.

Fig. 2 is the same as Fig. 1, only the apparatus g is shorter, and more powerful on this account, and the tube S has a bend which after the operation of washing or cleansing the pit or reservoir A would fill with water or disinfecting-fluid. In such a case a water-cork would be produced in the bend between the st-reet service-pipe T and the impurity-reservoir A.

Fig. 3 represents the same pit or reservoir A as described, with the difference that g is a hermetically-closed horizontal box, with-a valve, K, provided with a lever which is opened by the pressure of water or disinfecting-fluid working through the tube m .on a piston contained in the cylinder m, the piston being provided with a' rod, n, which presses down the lever of the valve K, thereby opening it. When the cock Mis shut, the pressure on the cylinder is relaxed and the valve ICO K allowed to shut through its own weight.

The ejector H and the perforated ball 0 work in this case as in the figures above described. This way of emptying the pit or reservoir A 5 is merely another mode of construction and working of the apparatus 9.

Figs. 4, 5, and 6, respectively, represent the pit or reservoir A, as described; but instead of opening and shutting the cooks M and N by hand,sel f-acting valves are provided, which are opened and shut by means of floats traveling along a rod, 1). The floats rise or de scend in the reservoir A according to the rise or fall of the level of impurities. I In Figs. 4. and 5 a disk, q, fixed to the float P, is caused to open the valve M by acting on its lever, and to close it through the weight of the float when descending by means of the chains r. The valve N is opened when the float is almost at the bottom of the reservoir A, and when the float quite reaches the bottom of the pit or reservoir A the weight of the valve N causes it to be closed again, the length of the chains being regulated as required.

Fig. 6 shows an arrangement wherein the valve M is worked by means of a floating ball, Q, while the valve N has a float, I, with movable hooks, which, when the float P rises, pass the lever of the valve N; but when the float 30 P descends they catch the lever of the valve N and pull it down till the lever gets out of their reach, through the float P descending to the bottom of the pit or reservoir A. Then the weight fixed to the valve N causes this valve 5 to be closed, and the lever regains its former position.

Fig. 5 shows, besides, a disk with a funnel, 20, inserted in the ejector, which can be adopted in all cases Where the impurities are not of a very solid nature, as it increases, to a certain extent, the power of the ejector H.

\Vhat I claim, and desire to secure by Letters Patent of the United States, is-

1. In apparatus for evacuating cesspools or impurity-reservoirs, the combination of the pipe I, furnished with valves M and N and branch pipe L, for admitting water or disinfecting-fluid underpressure, with the vessel or apparatus 9, ejector H, and pipe S, for transmitting the impurities from the vessel or apparatus g to the street service-pipe or sewagepipe T, and with the perforated hollow ball, 0, for cleansing the pit or reservoir A, all substantially as and for the purpose or purposes described.

2. In apparatus for evacuating cesspools or impurity-reservoirs, the combination of the pipe I, valves M and N, and branch pipe L, with the self-acting mechanism working by means of a float, P, for opening and closing the valves M and N, together with the ejector H and pipes S and 'l, substantially as de scribed.

3. In apparatus for evacuating cesspools or impurity-reservoirs, the ejector H, with a funnel, x, in combination with the vessel 9, pipes I S, and sewage-pipe T, all substantially as and for the purpose herein set forth.
